I deal with this from March to November every year. Get a good supply of water, food that keeps well, batteries for radio/flashlights and be careful with candles.
Last hurricane to hit here? no power for they said 8 weeks (was back in 3) water was shut off, stores and gas stations closed so no food. BBQ is where I cooked my food, made coffee etc. Not something I want to do again. As soon as the airport opened (week later) I was outta here.
